Title: Innovations of Eugene P Johnson
Introduction
Eugene P Johnson is a notable inventor based in Arlington, MA (US). He has made significant contributions to the field of technology, particularly in the areas of magnetic recording and motor control systems. With a total of 2 patents to his name, Johnson's work has had a lasting impact on the industry.
Latest Patents
Johnson's latest patents include a magnetic tape recorder/reproducer designed for ratio recording with synchronization. This innovative data processing system synchronizes an internal clock with an external clock, allowing it to be integrated into magnetic reproducer or recorder apparatus. The system employs ratio encoding schemes to convert conventional data into encoded data for recording on magnetic media. It also has the capability to read encoded data and convert it back into conventional data, utilizing the synchronized internal clock as the time base for ratio encoding.
Another significant patent is an arrangement for controlling the speed of a motor. This motor speed control system senses the back EMF of the motor in all operating modes, using it as a measure of motor speed. The design compensates for commutator ripple caused by varying rotor resistance through resistor adjustments associated with an operational amplifier. The output of the amplifier provides an average value of the back EMF without distortion. A comparator then compares this output with a reference signal indicating the desired motor speed, applying an error signal to a driving circuit that adjusts the motor's current to minimize the error.
